Work easier and faster with the good looking and improved UI

CODE 21.11 comes with a significantly faster and better looking user interface..A major improvement for all users.

The new major CODE release is recognized immediately from the brand new Sidebar

Ease of use is enhanced with both a performance and usability improvements. Leveraging our expertise in the mobile space, the Sidebar is built locally by the browser which is fast. Thanks to snappy and responsive buttons and controls, the Sidebar is intuitive and easy to use. This approach reduces the data transfer from the server to the browser. In addition, the widgets can be styled using the same CSS as other UX components, enhancing the look and consistency of the Sidebar across multiple platforms.

The Sidebar is now drawn directly on the screen by the browser through JavaScript, and no longer constructed on the server and then send to your browser. Earlier versions rendered the Sidebar as images on an HTML canvas. CODE 21.11 uses JSON files with the information of the Sidebar, an approach that we had applied earlier for the mobile implementations.  This approach reduces the data transfer from the server to the browser, and also the widgets can now be styled using the same CSS as other UX components, enhancing the look and consistency of the sidebar.

CODE 21.11: Fast & responsive “native” Sidebar

New handsome view functions in the NotebookBar

New buttons in the NotebookBar improve viewing documents. Zooming, full-screen view or switching the sidebar on and off are now accessible via clear buttons in the layout tab, and no longer only via the status bars or the burger menu. The NotebookBar makes these frequently used functions even more easy to find.

A major release with many performance improvements

CODE 21.11 brings together many performance improvements that we have been working on through the 6.4.x lifecycle as well as some more advanced optimizations. These are rather hard to screenshot for your viewing pleasure for obvious reasons, but the next two images are a try at least.

There is a lot to tell on the subject:

  • Asynchronous save
  • accelerating of JavaScipt
  • saving network traffic
  • improved multi-user editing
  • specifically in spreadsheets, we speeded up auto spell checking and AutoFilter.

Improved multi-user editing

One of the test-cases we use, generates text at around ten times the speed of a normal typist. This is something we have been optimizing along with scalability to larger numbers of concurrent editors of the same document. Read more details here, or a deeply technical blog on optimizing for a larger number of users. Or simply watch this video of a torture test of an intense multi-user editing session showing old, 6.4.x, and 21.11 versions from top to bottom.

Optimizing pathological loads – old/6.4.x/21.11

Don’t miss all details in the special blog post!

We publish a specific blog post with more interesting details, ready this week. I can be found here. It is mostly technical but comes with some nice graphics too. Make sure you do not miss it. Follow our announcements on social media (see the footer of this website).

Improving performance is ongoing work! We continue to work to profile and optimize uses-cases that are important to our users, the upcoming 21.11 micro-releases will exhibit more continuous improvement in this area – as well as ongoing improvements to our document pixel compression to make things even faster and lighter. It is well worth staying up-to-date with the latest releases.

Spreadsheets benefit with Excel compatible formulae improvements and extensions

Relentless focus in Calc to extend interoperability with Excel, and to add new functionality do show. Support for sheet-local scoped names has been added to INDIRECT(), and both TEXT() and OFFSET() have been is adapted to various corner cases to behave identically to the competition. TEXTJOIN() and CONCAT() now handle array & matrix arguments row-wise for improved compatibility. In addition, functions that use powerful regular expressions now correctly honour case-insensitivity flags.

PowerPoint PPTX Interoperability boosted

PPTX import improvements include managing images within forms – even those converted to greyscale or mirrored – are displayed online true to the original. This had been implemented in Collabora Office before.

More attractive and realistic shadow effects also enhance interoperability

A new Blur option does now allow for a more realistic rendering of shadows. The options of the feature can be accessed via the Shadows tab in the Area dialog or directly through updated “native” Sidebar.  This feature was initially developed during a GSoC20 for the LibreOffice project mentored by Collaborans and then implemented with further refinements in Collabora Office 21.06 and is now also available online.

Glow and Soft Edge effects for shapes – more than just interoperable

New features manipulate shapes in a more granular way. Once a shape is selected, you can choose the radius of the Glow effect and its Soft Edges within the sidebar using the Effects parameter. You can select the colour and the degree of transparency of the effect.
Not that these interoperability features apply to all shapes across Writer, Calc, Impress and Draw.

Version 21.11 – The new CODE release of the year

Starting with CODE 21.11, we are adopting the numbering of our online office suite to the scheme of our desktop product. The version number indicates the year and month of the first release of the current major version. CODE releases a major version annually and updates with fixes and improvements at approximately monthly intervals. As before, the updates are marked with a third consecutive number. We think that this kind of numbering makes it easier for CODE users to keep track of the versions.

Improved language handling in Writer

The basic model of language annotation that CODE had inherited from the LibreOffice core is that languages are explicitly assigned to regions of text. This can easily lead to unexpected results when documents that have been created in one local language (without specifying it further) are opened by another user with a different local language setting. Instead of a powerful but potentially confusing “multi languages” result, Writer now resets the language to the user’s UI locale if no document language had been defined. This more consistent behaviour was previously implemented in Collabora Office on the desktop, and is now also available online in Writer.

Shadowed tables for use in ODS and PPTX presentations

Shadows are now available for tables within presentations through the Table Properties dialog. The newly added shadow option includes different parameters such as blur and transparency.

Thanks to the Community!

Before we conclude with some final improvements and news, we really want to let you know about all the people that did the hard work, luckily often with joy and fun too, the community that made this release possible!
Shortly  before this release, we celebrated the wonderful work of these people in this blog  post. Do read it and join us in saying thanks!

Miscellaneous changes

In addition to the larger features, there are of course a large number of smaller changes:

  • Internet Explorer 11 dropped. This saves some rather significant code complexity in some areas eg. copy-paste, simplifies testing, and removes legacy JavaScript polyfills.
  • Auto-cleanup on by default. We now by default are more aggressive towards processes that are idle and are consuming a large amount of CPU, after around five minutes of this behavior they are killed, to disable that checkout the cleanup section in coolwsd.xml.
  • cool conversion. We have migrated our legacy loleaflet and lool paths to browser and cool – which impacts a number of configuration files and binaries. Integrators should continue to use the URLs they receive from the hosting/discovery end-point. Those with HA setups may need to update their proxy configuration with a simple search & replace as/when we do our enterprise COOL release. Generally we have back-compatibility symlinks to make this migration process smoother and simpler.
  • Quarantine. We now have an experimental way (disabled by default) to slowly accumulate files which caused a problem with Collabora Online in a quarantine directory. This can help report issues see thequarantine_files section in coolwsd.xml.
  • Notebookbar by default. Integrations can now change the look and feel of Collabora Online easily, so we have added a new state default state to our user_interface setting to go with the classic vs. notebookbar options to allow using the integration’s default.
  • Dropped deprecated reuse_cookies. This setting was originally a workaround to aid with authentication, prior to having access_token. However, it proved much less useful than originally anticipated, primarily because cookies nowadays have security restrictions in browsers.
  • Initial simple OT undo/redo. In place of falling back to our ‘repair’ mode, we can now undo and redo simple edits in writer to different paragraphs which were made out-of order.
    Surprisingly this  has never been requested as a feature, but we made a start here.

CODE 6.4.6 Introduces Fontwork, Gutter Margins and More Improvements

The latest version of the Collabora Online Development Edition (CODE) 6.4.6 introduces new features and improvements. The newly introduced Fontwork feature, allows you to create the well known graphical text art objects inside Collabora Online. The feature can be accessed via the Insert tab, both on the NotebookBar and in the classic UI. The Fontart Gallery allows you to choose from a set of different text art objects, each of which can be customized via the Sidebar. It is now also possible to define gutter margins. And of course there is more!

Use the latest features now – and do give your feedback

CODE gives you the latest and greatest features in online collaboration earlier than the supported version Collabora Online. Of course, we would love to hear about your experiences. Please leave your feedback on CODE in the community forum or report any possible issues on GitHub.

How to use the attractive Fontwork objects

Working with Fontwork in Collabora Online is very straightforward. After choosing a Fontwork object from the gallery, double-click the object to update the text. When selected, the colour, transparency, and the orientation of the graphical text can be adjusted through the Sidebar. The new Fontwork panel makes it easy to work with the characters’ height, or change the alignment and the character spacing. If you are using Collabora Online via your mobile phone’s browser you will benefit from the mobile-friendly interface, as shown in these images.

The main colour of the Fontwork object is defined by the Area colour, similar as to when working with Shapes. You can also choose from different types of fills (e.g. colour, gradient, bitmap, pattern) and set the transparency. Secondary or tertiary colours of Fontwork can be defined through the Line or Shadow colour.

Easier and better page formatting in Writer with Gutter Margins

Writer now features improved support for gutter margins. This is often requested for government documentation and really popular among our users in Asian countries.
Mind that this new feature is not yet available in the Writer on desktop. You can test it on desktop though, with the unstable snapshot of our supported Collabora Office version. And the work is of course also committed for the next LibreOffice release.

How to use the new gutter margins

This margin type can be specified explicitly, and it is also possible to select whether the gutter should be located on the left or at the top. The feature works with mirrored margins as well and is very useful for printed publications. To utilize this feature, access the Page Style dialog through the Layout tab. In the Page dialog you will find a new Gutter option below the Margin settings. On the right-hand side there is a drop-down menu that lets you choose the Gutter position (left or top). The small page icon in the dialog renders a preview of the margin size.

Microsoft Word also includes a gutter margin option, so this feature is also an interoperability improvement. When importing or exporting documents, this feature is now supported with DOCX, DOC, ODP, and RTF formats. While the feature has been primarily developed for Collabora Online, it is also available in the desktop version. If you are interested in more, and technical, details of this implementation, please take a look at the blog by developer Miklos Vajna.

1. Define the size of the gutter margin
2. Choose the position of the gutter margin
3. A preview of the gutter margin’s size and position is rendered in the dialog


New configuration option for integrators

Collabora Online now does support the FileUrl property of WOPI. This is a URI to the file location that the WOPI client uses to get the file and can be used to get the file instead of a GetFile request. FileUrl brings better performance in some configurations and has been implemented in cooperation with partners.

Thank you for your support in 2020!


It is a good tradition at the end of the year to reflect on what we have achieved as a team and together with our partners and the community, and remember with gratitude all the hard work that so many have put in.

Of course, this year was marked by the worldwide Corona pandemic. Early during the outbreak, we had published a statement on how far Covid-19 affected our work. Even though our structure – most of our team works remotely from the home office – meant that we were much less affected by difficulties than other companies, we too have friends, colleagues and relatives whose health were affected and also have kids we had to homeschool this year. Nevertheless, this has not affected our customer’s support, and there has been a significant up-tick in interest from people who want to collaborate on their documents without surrendering their data.

Despite all challenges, 2020 has been a very productive year at Collabora. We released important major releases for all our products – Collabora Online actually even saw two major releases, and Collabora Office arrived on Android and Chrome OS. Although conferences have only been possible online since March, we could present ourselves and our work quite well there. By moving to GitHub, a lot of fresh air and many dedicated people got in touch with Collabora Online.

Here is a summary of what we achieved together!

Collabora Online – two major releases, many improvements

The year 2020 saw two major releases of Collabora Online introducing handy new features and substantial UI and UX improvements.

Collabora Online 4.2 brings the feature rich Sidebar

In March, we introduced the Sidebar to Collabora Online 4.2. The versatile Sidebar hosts many of the most used features and provides a much improved user experience for the PC browser.

A version packed with new features

With Collabora Online 4.2 we also introduced an enhanced Colour picker with Conditional Formatting and the Function Wizard in Calc. We also added rich copy/paste, made working with images and tables much more easy and added the possibility to configure the Table of Contents. Find all the details in the Collabora 4.2 announcement.

Exciting 4.2 updates throughout the year

Many updates followed throughout the year:

  • April: brought improved PDF handling and support of Asian date formats in Calc in version 4.2.2.
  • May: Support for dropdown lists in form fields in ODT & DOCX and other text file formats and the handling of tabstops directly on the ruler in version 4.2.3
  • June: Multiple slide selection on slide pane, handling of tab stops, improved word count on phones and many other features arrive in version 4.2.4

Collabora Online 4.2.9: New options in comment threads

Collabora Online 4.2.12: Edit Chart titles from the Sidebar


Collabora Online 6.4 introduces the NotebookBar


In November, we released Collabora Online 6.4. This version introduces the (optional) new NotebookBar with its well-organized tabs and the possibility to collapse it to save space.


Collapse the NotebookBar for more space


This version also included leap in version numbering. This aligned with our desktop version and now reflects more accurately the level of development, since much of the technology is shared by both products.


Collabora Online 6.4 added many new features like the possibility to freeze panes in Calc, many interoperability improvements like, transparent text (in both Impress and Writer) and gradient backgrounds and better SmartArt import in Impress. Find all the details in our announcement.

Collabora Office sees a new major release and powerful updates

In August 2020, we released Collabora Office 6.4. Our business-hardened and long term supported LibreOffice derivative brought a number of practical improvements to the workflow on desktops.

Security, encryption, PDF – new features on the Desktop

Naturally we had back-ported many of the new features to our supported Collabora Office 6.2 release as updates.

Padded Numbering was one of the results of this year’s hack week at Collabora and premiered in Collabora Office 6.2-9. Later this year it became part of Collabora Office 6.4 and LibreOffice.

Collabora Office 6.2-9: Padded numbering

In July, introducing the possibility to send encrypted PDF with Mail Merge, we added a privacy option to Collabora Office 6.2.-21. This also became available in Collabora Office 6.4 and LibreOffice.

Thanks to the success of our mobile apps, we have expanded the LibreOffice user base by half a million mobile installations, as can be read in our annual LibreOffice infographic.

Adding more features to the mobile devices

Throughout the year we kept adding important new features to the mobile devices like tab stops & page set-up panels, improved word count, support for Asian fonts, and the possibility to open password-protected documents.

Collabora Office for Android & iOS 4.2.3: Page setup panel for text files on phones

Version 6.4 – Another major release for mobile devices

The work on our mobile apps had its climax in the release of Collabora Office 6.4 for Android & iOS in November, which brought new features (e.g. gradient backgrounds, transparent text) from Collabora Online to mobile devices and introduced the NotebookBar to tablets.



Collabora Office for Android & iOS 6.4: The NotebookBar becomes available on tablets
Collabora Office for Android 6.4: The first Darkmode elements are beeing introduced

Collabora Office for Android & iOS are now available via the Play Store & App store. Additionally, we also offer an .apk file for download and made the repository available on F-Droid.

Collabora Office ships on Chromebooks

After making Collabora Office available on Android, this summer, we completed our multiplatform strategy by making Collabora Office available for Chromebooks as well.

The Chrome OS version is also available via the Play Store and is now also available as version branch 6.4. Interested in the technical background? Check that out in this talk:

The release of CODE 6.4 also marked the beginning of our initiative to lower the barriers to join the project. A few weeks later we announced moving the source code of Online to GitHub making it easier for interested people to get involved, and tackling some of the intriguing community marketing problems we faced.

The community rocks

This year we invested a lot of time, effort and passion to make Collabora Online & CODE a more accessible and fun project to work on. We created a forum for users to find support, many easy hacks and assigned developer Muhammed Kara as a community mentor, helping people getting on board. Why are we doing all this? Read about it in our FAQ!

LibreOffice developement Workshop in Eskişehir

Collabora sponsored an impactful four-day LibreOffice development workshop during the Free Software Winter Camp at Anadolu University in Turkey. We wrote an article about the impressive results. Two participants of the workshop later went on to work GSoC projects for the LibreOffice project.

Google Summer of Code 2020

In addition to the Collabora Online community, our developers were very committed to this year’s Google Summer of Code. Read about the LibreOffice projects we mentored and the successful new implementations that resulted from these GSoC projects. Participants in the Google Summer of Code often become long-term contributors to the project.



In summary, it has been a busy year here at Collabora Productivity. This overview only sums up a small part of the great things we have been working on alongside the community. We have advanced our mission to make open-source rock; giving users privacy and businesses control over their data. We not only produced excellent results, but also had a good time working on these things – despite the challenging conditions that 2020 offered. If you’d like to get involved its easy to partner with us, buy from us, or get involved in the growing Collabora Online community. We have lots of plans in the pipeline for 2021 and hope there will be more possibilities to meet in person on conferences and on events. We would like to thank the whole team, particularly our great partners, and customers who make our work possible, and the community of developers and users who make it fun. We look forward to continuing the successful work with you in 2021! Have a very Happy Christmas & a peaceful New Year.

Thank You!

Background information

Collabora, a leading contributor to the LibreOffice codebase and community, is the driving force behind putting LibreOffice in the cloud. Initial development started back in 2011 and four years later, in 2015, CODE (Collabora Online Development Edition) was created, allowing people to check out LibreOffice in the cloud for the very first time. Shortly after this, the first production-ready Collabora Online was released.

We encourage people to contribute. While Collabora has done more than 95% of code commits so far, we are glad that since the move of collaboraonline to github more people are getting involved. Maybe you can join too?
